Pro auto disk wth 2230 powder on a Load Master

Postby zmmnm3 » Thu Nov 25, 2010 6:01 pm

I have a Pro auto disk that I use for all of my powder with a Load Master. I get great results and ease of use except for 2230 which is a fine ball powder. Regardless of adjustment, I get spillage every so often with powder all over the shell holder and a very low charge in the cartridge. I took everything apart and cleaned the dies but I don't see any issues.

Anyone have any similar experiences? Is it because of the 223 cartridge? Is ball powder the issue?

Appreciate any help.

Welcome.

Yeah the fine ball is leaking out the sides probably. Someone here started a thread on lapping the 2 conical surfaces, that helped me a lot. It also helps make a smoother operation of the measure.
(edit: duh, it not a pro powder measure, sorry, I cant read)

Another issue is to clean the drop tube on the inside with alcohol. Lee ships all products with an oil coating, you could be getting some bridging on the sticky surface.

The disk measure I have not had a problem with ball, but with stick I have had it get stuck open once. Are you using the spring or the chain return method? I assume you are using the double disk kit? Did you reset the internal brass bushings for small rifles???

A little more info. It appears it is a timing issue with expander not correctly setting in the cartridge. I cleaned the interior with alcohol and it works better. I also re indexed the carrier.

I also changed out the pro and went back to the plain disk powder measure with a lot better results. It is something with the Pro. I am using one disk for powder a 1.46 that drops the right amount of powder. Not had too much luck with the double disk system.

Ball is a pain. However, when all is working as designed it is great.

Thanks for the reply.

try pulling a used fabric softener sheet through the drop tube. It will reduce static which will cause powder to hang up.

I use a lot of AA 2230 with a double disk kit for my 223. I really like the stuff, leaks a small amount, not enough to get me excited enough to work on it.

Note: I have worked up a load with the new IMR 8208 XBR powder. It's looking pretty good for two of my 223s. If it ever gets warm in Iowa again I'll get on the bench rest and post the results.

I'm just getting set up to load 223 and thought I might use Varget. Do you have any experience with Varget? I'm going to load for my Ar15.

A couple years ago I 223ed a lot of prairie dogs with 50 grain Sierra Blitzkings loaded on top of Varget. They were loaded on a blue machine, don't remember what the load was. It was a very consistent shooting round. Varget got pretty expensive for the quantity of rounds we shoot, so we switched.

Powder Valley has Varget for less than $17 a pound (in 8 lb size) and I live less than 40 miles from them so no hazmat. Works out to be a hair over 7 cents a load. That's in my budget. AA2230 figures out to be almost the same per round (AA2300 - 122/8#); so less than a penny per round difference + PV is Out Of Stock on 8# AA2230. So I think I will stay with Varget.
Thanks;

I am currently loading .357SIG with AA#7. I have the same problem, leaks all over the place but... the charge getting into the case seems to be consistent within .1gr.

The guys on AR15.com love varget.

I use AA2520 because a friend found a terrific deal about 3 years ago.

I have also used H335 (55gr to 65gr), and H322 for 75gr.

I like H322 but its expensive, so only for heavy bullet target rnds.
(great for 308 also)

I will probably buy more H335 next time.

Just returned form the range and the 2230 load shot great. Regarding the leakage switching to the standard disk powder measure made the difference. The groups shot today were great. I did not have my chrono today but the last time I checked the load with 21.5 gr produced about 2400 FPS with a 62 gr bullet.

On your pro disc measure, take it apart and check the little rubber wiper on the bottom and make sure it's still in good shape. If it is, you may try some fine sandpaper on a flat surface to lightly sand the bottom of the measure. Make sure to remove the elastemer ? wiper beforehand. This worked for me, no leaks even with ball powder.
